Title: Photo voltage sensor
Inventor: KUMEGAWA HIROSHI
IPC: G01R15/24
Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To improve the temperature characteristic of a photo voltage sensor not by a sensor structure, but by selection of electro-optic crystal. SOLUTION: This photo voltage sensor 1 is so constructed that a polarizer 4, a λ/4 plate 5, a Pockels element 6 which is an electro-optic crystal and an analyzer 7 are sequentially arranged along the advance direction of light. In this case, the electro-optic crystal to be used is selected in such a manner that the allowable value of a measurement error is taken to be β, and the refractive index of the electro-optic crystal when the impressed voltage to the electro-optic crystal is zero is taken to be n0, the variation of refractive index is β.no/6 or less. Thus, the measurement error is within the allowable value β so as to enable high accuracy voltage measurement. In the case of BGO crystal with n0=2.54, the measurement accuracy of 1T grade can be secured by selecting a member, the refractive index of which varies within 0.4%.

Title: Rainwater control cover
Inventor: TOKUMURA AKIRA
IPC: E04F10/08
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To prevent the adhesion of dirt due to dropping of rainwater around a recessed and projection sections on a wall while maintaining flatness of an outer wall of a building. SOLUTION: A rainwater control cover having a face 11 which is tilted in such a manner that it leaves an outer wall 30 as it draws downward is attached just above a window frame 40. The length of the outer wall of the cover along the horizontal direction is larger than the length of the window frame. Rainwater which descends along the wall from the above of the wall does not flow in an upper section of the window frame 40 and flows on an inclined face 11 of the cover and is discharged to the outside of a building. Consequently, since the flow of rainwater is not deviated and collected, dirt due to rainwater does not adhere on the outer wall.

IPC: F15B15/10
Filed: 1991-10-09
Abstract: PURPOSE:To provide a flexible pressure deformation element which is suitable for use as a micro-actuator, capable of being small-sized, capable of predicting its deformation by simple analysis and suitable for mass production. CONSTITUTION:In a tube 1 of an elastically extendible and contratible material, both ends thereof are closed, so that a chamber 10 capable of holding working fluid is defined.

IPC: H01J9/14
Filed: 1987-11-18
Abstract: PURPOSE:To improve material utilization efficiency and reduce cost by arranging a rectangular or square shaped frame on the periphery of a mask frame and giving tension to the shadow mask. CONSTITUTION:A rectangular frame 25 is arranged on a support plate 24. The inner dimension of the frame 25 is set to be larger than a mask frame 14 while its outer dimension is set to be smaller than the inner dimensions of rectangular openings 22, 23 of depression plates 15, 16. When a vertical feed device 30 is operated, the support plate 24 moves to come near to the depression plates 15, 16 and a tension is applied to a shadow mask member 131 while being bent by the rectangular frame 25 according to the relationship between the rectangular frame 25 and the depression plates 15, 16. An unnecessary part of the shadow mask member 131 is then cut off. In this case, the area of the unnecessary part of the shadow mask is 25% compared with the case in which conventional circular frame is used. This increases the utilization efficiency of the material and reduces the production cost.

Title: Switching power source circuit
Inventor: YANO YASUSHI
IPC: H02M3/155
Filed: 1989-11-06
Abstract: PURPOSE:To provide the capacity of a capacitor irrespective of the constant of a controller by providing a series circuit of mainly a resistor, the capacitor between an input DC power source and an output power source. CONSTITUTION:When an input DC power source 1 voltage is applied, a current flows to a resistor 10 and a capacitor 11. If the terminal voltage of the capacitor 11 is low, the conducting time of the switch 2 is very short since the output of an error amplifier 8 is connected to a diode 12 and an output power terminal 15. When the voltage between the terminals of the capacitor 11 is raised by the resistor 10, the conducting time of the switch 2 and the voltage between the terminals of the capacitor 5 is raised. The terminal voltage of the capacitor 5 is controlled constantly by a comparator 6. The capacitor 11 is charged by the source 1, and the diode 12 is interrupted. Since the series circuit of the resistor 10 and the capacitor 12 is electrically isolated from the output of the amplifier 8, the capacity of the capacitor 11 becomes irrespective of the constant of the controller.

Title: Fine flow rate valve
Inventor: ISHII YOSHIHISA
IPC: F16K31/06
Filed: 1992-09-17
Abstract: PURPOSE:To prevent the clogging in a narrow slidable surface by securing an exceedingly small flow rate by forming the inside of a slidable fitting surface as water flow passage and sliding the slidable surface when a solenoid valve is opened and closed. CONSTITUTION:A flow rate control body 3 constitutes a slidable surface with a valve body 9, and a liquid seal 4 is made of rubber and prevents the leak of liquid, together with the operation of the valve body 9. The inside of a housing 1 is partitioned to chambers 5-8 by a valve seat 2, flow rate control body 3, and a liquid seal 4. Further, a spring 12, water inlet 14, and a water discharge port 15 are installed. In the first stage, a flow passage is closed by the valve seat 2 and the valve body 9, and the chamber 5 is applied with a water supply pressure, and each inside of the chambers 6 and 7 is kept at the atmospheric pressure. When an electromagnet 11 electrically conducts, a permanent magnet 10 and the electromagnet 11 repel each other, and the valve body 9 moves rightward on the figure, and the dust adhering on the slidable surface of the flow rate control body 3 and the valve body 9 is removed. When the valve body 9 separates from the valve seat 2, the water at the water inlet 14 starts flowing, and the inside of the chamber 6 is applied with the water supply pressure. Since the slidable surface of the flow rate control body 3 and the valve body 9 is exceedingly narrow, the flow rate becomes exceedingly small.
